Summary
Saint Petersburg State University
education research university legacy
ASN-SPBGU is the network of Saint Petersburg State University (SPbGU), one of Russia's oldest and largest universities.
What it's used for
- Campus networking across the university's faculties, institutes, and campuses in Saint Petersburg.
- Research computing, teaching, library, and administrative services, plus student and staff internet access.
Notable
- The address space is substantial for a single institution, reflecting a multi-campus university that historically assigned public addresses widely rather than hiding hosts behind NAT.
- Institutional space like this behaves very differently from consumer ISP ranges: addresses tend to be long-lived and tied to identifiable buildings, labs, and services rather than churning between subscribers.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
8 upstream, 1 downstream and 11 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-12, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,769 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
